MX3D, a Dutch robotic manufacturing technology startup, is celebrating the completion of its revolutionary 3D printed steel bridge. It will soon be installed over a canal in Amsterdam. Creating the bridge required years of design, engineering, and coding. Printed from over 9,000 pounds of stainless steel, the bridge represents an innovative application of this traditional structural material.
MX3D wanted a way to showcase its ability to print large-scale functional objects with durable materials. The bridge demonstrates the possibilities while combining the old with the new. Amsterdam’s old canal system will be paired with the latest in 3D printing technology in this artistically interesting but functional bridge.
How it was created
Using a combination of welding machines and coding, six-axis industrial robots were created to print the bridge. 3D printing, or additive manufacturing, creates a product by adding layer upon layer of material. This is generally done on a small scale, inside a box on the printer. The pedestrian bridge is something different altogether. Printing into thin air, the robots created the bridge one layer at a time.
The entire process required collaboration between the fields of construction, technology, engineering, and design. Designer Joris Laarman explains the constant need for revision before production could proceed. At each step, factors such as safety, practicality, and durability were questioned and tested. Models of the bridge were created and re-created. Actual 3D printing on the bridge did not start until a year and a half after the process of creation began.
How it will be maintained
Technology takes the lead in monitoring and maintaining the structural integrity of the footbridge. A sensor network will track displacement, strain, and vibration. It will also track and record the temperature and air quality around the bridge. Later, the network sensors will also track pedestrian speed.
Using data recorded by the sensor network, a virtual model of the bridge will be created and monitored in the lab. This process will assist future efforts to create and monitor 3D printed bridges.
MX3D has won two awards this year. They are both awarded to companies that display forward-looking design and techniques.
The bridge won the Dutch Design Public award for 2018. “The form and material freedom achieved by the design hint at almost unimaginable scenarios,” the Dutch Design awards website states.
MX3D is also a STARTS award (S+T+ARTS=STARTS – Innovation at the Nexus of Science, Technology, and the ARTS) winner this year for the bridge project. The jury that granted the award issued a statement that expressed its thoughts on the bridge project: “(The) 3D-printed metal bridge is a really important marker for the future of architecture and construction.”
In the future
Engineering and technology professionals will be watching and waiting as the bridge is installed and used in Amsterdam. Monitoring and maintaining the bridge may prove to be another challenge. With each new advance in technology, some difficult challenges can be expected. This bridge offers many opportunities to learn more about the potential uses and qualities of stainless steel.
By bringing 3D printing “outside the box“, MX3D explores the unknown. Stainless steel has long been used to create structurally sound objects. Printing these objects is stepping into a new frontier in engineering, design, and technology. “A world of new opportunities is in front of us but we can only just see its contours,” says Laarman. Previously unknown uses of stainless steel may arise as technology and manufacturing continue to collaborate on large projects.
Straws have definitely been causing a quite a stir lately. Pun completely intended.
Plastic straws are everywhere. From the local coffee shop to our favorite smoothie place. Most of us pick up these items without even considering the environmental impact of one-time use plastic products. Unlike some other materials, plastic can take up to 1000 years to decompose in a landfill.
The recent plastic straw ban aims to change this, ordering business to nix plastic straws by 2020. Many plastic products, including straws, can be washed into the ocean and significantly injure marine life. With local governments expediting this change, many are scrambling to find alternatives to plastic straws.
Where do we go from here?
For many, giving up the use of straws is simply just not an option. How can you drink your favorite boba tea without a straw? Fortunately, with the purchase of a reusable straw, you can enjoy your boba tea and save the environment at the same time.
When it comes to reusable straws, you will most likely have to decide between bamboo, silicone or stainless steel. Reusable straws are made from several materials, but bamboo and stainless steel appear to be the most popular.
While both types of straws decrease our dependence on plastic, stainless steel seems to be the prime option.
Bamboo is more delicate than stainless steel, so the bamboo straws are more likely to get damaged in your backpack or purse. Stainless steel straws also last quite a bit longer than bamboo straws. These straws can last as long, and in some cases even longer, than regular stainless steel cutlery.
Bamboo straws will need to be replaced every few months to years, depending on the amount of use.
The University of Guam’s Sea Grant Program, an initiative focused on restoring clean oceans, suggests stainless steel straws are the best place to start.
Taking care of your reusable straw
Washing your straw at home is quite straightforward. You can rinse the straw with hot water and disinfect with soap. If you have a stainless steel straw, it is also dishwasher-safe. It really can’t get too much simpler than that!
Using the straw while you are out may take a bit more planning. After you use the straw, make sure to rinse it under warm water. You don’t want liquid from your sugary drink getting stuck in your straw. After the rinse, you can just put the straw back in its’ pouch and take it home to be washed. No muss, no fuss.
Change starts with us…
Each day we make small choices that can either negatively or positively impact our environment. If all work towards using fewer plastic straws we can make a significant difference in the health of the planet. When all of us come together with a common goal, you would be amazed at the impact that we can make.
Stainless steel cutlery, silverware, and drinkware is rising to popularity for its durability, strength, ease of use, and eco-friendliness. By making a stainless steel straw a token accessory you take with you, you could inspire others to do the same.
One hallmark of a true artist is being able to create beauty out of anything. While certain artists might have preferences for one medium over another, there are some that never go out of style. Clay is definitely one of these, and paint is another. Metal statues and sculptures have also always had a place in traditional art. Recently, stainless steel has grown in popularity. Artists have crafted a number of impressive pieces in this material.
How Does Stainless Steel Become Art?
Art can be anything, or come from anywhere, and stainless steel is no exception to that rule. By its very nature, stainless steel offers a level of durability and versatility that is hard to find. Because there are so many options for finishes, it’s possible to create all kinds of art, ranging from the Dublin Spire to Balloon Dog.
Polishing a piece to a bright gloss, also called a mirror finish, can take days or weeks. As a result, it will help the piece last for a long time. Both Balloon Dog and Chicago’s Cloud Gate make use of mirror finishes. The original Balloon Dog is also an excellent example of the finishing technique for a drastically different color effect. An artist has many options when using stainless steel, making it a popular choice for sculptures and statues around the world.
How Does Stainless Steel Art Benefit a City?
The method of finishing a stainless steel piece can ensure its durability and longevity to a remarkable degree. Even if an artist decides to go the route of steel brushing, sandblasting, or heat treatments, the piece will still be sturdier than one made of marble or clay. A paint finish would bubble and peel. Fortunately, with the variety of options available for stainless steel, a paint finish is not necessary at all.
Given that stainless steel can be manufactured in several different shapes and sizes, and easily joined together, this also makes it a more cost-efficient alternative. A larger piece needs to be lugged around as one solid whole. Or, it can be carefully taken apart and reconstructed on site. This could leave noticeable marks behind. Many praise stainless steel for its reshaping abilities. With a little grinding and sanding after the welding, the piece will look like one finished whole.
Where Can I Find Stainless Steel Art?
There are stainless steel pieces everywhere. From The Seed Sculpture in Manchester to the Sibelius Monument in Finland, creative works by creative artists are everywhere you go. Depending on the artist, different techniques will come into play. Depending on the location, different grades of steel come into use.
For example, the Cones in Canberra, Australia might require a higher grade of steel than Turning the World Upside Down in Jerusalem. The Cones are a little closer to nature, and therefore more likely to deal with damaging elements. While pieces like News might have run at the forefront of the longer lasting steel sculpture trend, the evolution of the steel industry, and what we can do with it, has given rise to several alloys. Each of these is much more resistant to corrosion than the last.
As a sculpture trend, stainless steel is here to stay — and stay beautiful. It’s been a game changer from its earliest appearances, focusing on outlasting the environment, to the newer pieces that take advantage of modern technology.
In the recent past, China’s stock market has been dwindling due to the trade wars with the US. However, steel prices have been indicating a positive state of the economy. Although China is transforming from manufacturing to consumption economy, steel is still an essential part of the economy. For instance, Baosteel, one of the biggest steel manufacturing companies in the country, reported a sixty-two percent year-over-year increase in profits.
The steel market seems undisturbed by the numerous tariffs, internal economic issues, and government controls. For instance, according to the National Bureau of Statistics (NBS), steel production increased by 7.2% in July. Production in 2018 is ahead by 6.3% compared to the records set last year. The growth may have slowed slightly in August as the purchasing managers’ index (PMI) reduced by 1.4% but stayed above fifty percent.
According to the World Steel Association, China accounted for 49.2% of the global steel manufacturing. Recent data indicates that China accounts for 50.7% of the world steel production. China’s output in a month is more than the United States produces in a year.
Lower Production, Higher Prices
In the past three years, the government has been running a campaign to reduce production capacity. This is in attempts to curb environmental pollution. Also, the overproduction has been blamed for low prices and losses. In 2016, the government cut the annual production by sixty-five million tons. In 2018, by fifty million tons.
This year, the government is looking forward to cutting output by thirty million tons. Apart from the cut in production, the government has also been issuing temporary suspensions in the Beijing area. This is to prevent steel factories from producing fog during the heating seasons. However, the suspension that could have cut production by fifty percent is not deterring overall production. This is because production doubled in other parts of the country.
On the other hand, the downsizing and production cut attempts by the government caused steel prices to soar. Some steelmakers increased their production to take advantage of the rise in prices. According to the China Iron and Steel Association (CISA), there was a 14.6% increase in prices at the end of July.
Improved Production Process
Another reason for the increase in production is improved efficiency. Nowadays, most steel mills around the country use better grades of iron ore and more scrap steel to reduce emissions.
The good fortunes witnessed by the steel industry may be a headache to the government. Information from the National Development and Reform Commission (NDRC) pointed out that this year’s targeted cut in production might be difficult if the profit margins continue to grow. However, the government has been able to cut capacity of 24.7 million tons in the first seven months of 2018.
There have been reports that some millers may restart outdated production methods to take advantage of the soaring prices. For instance, many mills that had closed two years ago have recently started reopening due to the increase of steel prices in the market. Research conducted by the Greenpeace East Asia indicated that 73% of the increased capacity came from factories that were presumed idle. There has not been an official government audit to explain the increased production despite the measure put in place to cut output.
Efforts by the government to cut production are faced with a lot of challenges. For example, there have been reports that the price does not control the production of steel. Overproduction is continuing whether the prices are high or low. Additionally, steel production has been thriving even when the GDP is declining.
In order to transform sugar cane into white sugar, it must undergo a complex refining process. Brazil and India are two of the major players in the sugar industry. Both countries are currently engaged in upgrading essential equipment for sugar refinery to aid in eliminating waste and contamination.
An essential aspect toward eliminating waste is implementing stainless steel for all equipment used in making refined sugar and sugar cane juice products. Many business owners are currently making the move to upgrade their equipment, which is in the best interests of safety – as well as efficacy. The slight increase in cost for stainless steel equipment would quickly get recouped through the major increase in usable product available to sell.
Transforming cane sugar into refined white sugar takes the most effective, viable metal available. Stainless steel meets that criteria. In fact, the most hygienic metal for refining sugar cane is stainless steel.
Sugar Cane and Corrosion
Regular carbon steel rusts and corrodes when it encounters air and moisture. However, when you add chromium, it creates stainless steel – which is highly resistant to corrosion.
The juice of the sugar cane is quite acidic. In addition, it emits a gaseous discharge. Acid tends to consume most organic material. Gas turns toxic when mixed with many chemicals. Most materials corrode and break down against acid and gaseous discharge. Corrosion is one of the biggest problems facing the sugar industry.
Any company that uses equipment to handle sugar knows their equipment will wear out quickly when exposed to sugar cane juice. If the equipment contains moving parts, then corrosion eats through the bearings and mechanisms powering those parts. If the equipment is a free-standing holding tank with no moving parts, then sugar cane juice quickly erodes the holding tank’s material. This allows it to spread to other pieces of critical equipment when the acidic cane juice wreaks more havoc.
Responsible Companies Use Stainless Steel
Corroding equipment typically contains sharp edges. Workers and employees deserve a safe working environment. Sharp edges from corroding parts pose hazards and danger to the employees sugar manufacturers have a responsibility to protect.
A great deal of wasted productivity, as well as the amount of product lost, happens because of using carbon steel or another metal that cannot resist corrosion. Stainless steel includes a ferrous and chromium property to it that makes it highly resistant to corrosive products.
Most major manufacturers worldwide use stainless steel to make their products. Typically, stainless steel is preferred for processing food products. It is nearly impossible to maintain sanitary conditions without it. In 2007, 11 years ago, India lost an estimated $250 million dollars a year due to corrosion in metal factories. If India’s sugar barons do not convert all metal equipment used to refine sugar, they may find themselves priced out of the world market. As a result, a recent study has found that using stainless steel solutions will reduce corrosion-related losses and recalls in India by nearly 50%, a figure that is sure to entice numerous major players in the sugar refinery industry.
With the sugar industry being a crucial driving factor for development in a number of countries around the world, the transition to stainless steel will mean continued sustenance and prosperity for those regions.
